The Justice Department has issued grand jury subpoenas to Philadelphia District Attorney Larry Krasner’s office, tying a federal judge’s criminal referral to a live probe of possible obstruction.
Fox News reported that the subpoenas went out in recent days and that two sources briefed on them linked the demand for records to potential obstruction of justice in how cases were handled before federal judges.
The move lands more than a month after U.S. District Judge Paul Diamond referred Krasner and his top deputy, Matthew Stiegler, to the DOJ for a possible criminal investigation. Neither man has been charged. The legal stakes are plain: a sitting big-city prosecutor now faces grand jury process after a federal judge concluded he and a top aide may have broken the law.
Diamond’s referral grew out of litigation over a 2009 murder conviction. Dennis Johnson was convicted that year of killing Kenyatta Smith. In 2022, Krasner’s office filed papers saying Johnson was entitled to habeas corpus relief based on ineffective assistance of counsel, a detail the Associated Press reported and Fox News carried.
Prosecutors later flagged potential conflicts involving Stiegler and urged that the matter go to the Pennsylvania Attorney General’s Office. Diamond’s opinion described Krasner as opposing that handoff. Krasner repeatedly said someone from his office needed to remain involved to “protect the office.”
The judge did not stop at procedure. He wrote that evidence uncovered in the case could amount to false statements, perjury, obstruction of justice, and conspiracy. He disqualified Krasner and Stiegler from the matter. He declined to disqualify the entire district attorney’s office.
Diamond put his conclusion in blunt terms.
"I have thus reluctantly concluded that Philadelphia’s highest law enforcement official and one of his top assistants may have violated the law,"
Fox News reported that the opinion also described Krasner as warning of “consequences” if staff alerted the court to an internal conflict, and as pressing a path that kept his office in the case. The judge alleged that Krasner and Stiegler sought to pressure prosecutors into presenting a false narrative to the court. Those are the judge’s findings as described in the coverage, not adjudicated criminal verdicts.
Krasner rejected the court’s findings when the referral became public. He framed the dispute as unfinished business headed for appeal.
"I respectfully and vigorously disagree with the court’s findings of fact and conclusions of law,"
He added that he looked forward to appealing “as soon as the law allows,” and said the pending matter limited his and his office’s ability to respond in the media.
After word of the subpoenas surfaced, Krasner’s office did not immediately respond to a request for comment. The Justice Department declined to comment.
Grand jury subpoenas are compulsory process. They pull documents and testimony into a secret investigative channel. Two sources briefed on these subpoenas told Fox News they concern potential obstruction tied to case handling before federal judges, and that the papers followed Diamond’s referral of Krasner and Stiegler.
Public reporting has not named the specific grand jury or district that issued the subpoenas. Exact dates for the papers and for Diamond’s written referral are not in the public account beyond the relative markers “in recent days” and “more than a month after” the judge acted. Investigators will need to determine whether any statements or filings crossed into false statements, perjury, obstruction, or conspiracy as the judge flagged.
What is confirmed is narrower and still serious. A federal judge referred the city’s top prosecutor and a top deputy for possible criminal investigation. The DOJ then sent grand jury subpoenas to the DA’s office. Disqualification already removed Krasner and Stiegler from the underlying case while leaving the office itself in place.
The Johnson litigation is the factual spine. A 2009 conviction. A 2022 habeas filing from the DA’s office claiming ineffective assistance of counsel. Internal conflict concerns around Stiegler. A push by prosecutors to send the matter to the state attorney general. Resistance from Krasner, who cast continued office involvement as necessary to “protect the office.”
Diamond treated that sequence as more than a routine ethics dust-up. His opinion, as reported, described an alleged effort to steer what the court would hear. He paired disqualification of the two officials with a DOJ referral covering false statements, perjury, obstruction, and conspiracy. That package is what the sources now connect to the new subpoenas.
No charges have been filed against Krasner or Stiegler. A referral is not an indictment. Subpoenas are not a finding of guilt. The difference matters in a system that still requires proof beyond a reasonable doubt before anyone wears a conviction.
At the same time, federal judges do not lightly accuse a district attorney of possible crimes in a written opinion. Diamond said he reached his conclusion reluctantly. He still reached it. The DOJ’s decision to issue grand jury subpoenas shows the referral did not die on arrival.
Authorities have not publicly confirmed the full scope of documents sought, whether testimony has been scheduled, or how the obstruction theory maps onto specific filings and meetings. No public results have been released on charging decisions beyond the fact that neither man has been charged. The habeas outcome for Johnson is also not spelled out in the available account.
Procedurally, the next steps sit with federal investigators and the grand jury. They can compel records from the DA’s office, test the conflict timeline, and weigh the judge’s allegations against the evidence. Krasner has already said he intends to appeal the court’s findings when the law allows, while citing limits on public comment while the matter remains pending.
Philadelphia’s district attorney is the city’s chief local prosecutor. When a federal judge says that official and a top assistant may have violated the law, the conflict is not abstract. It cuts at the line between advocacy and candor to the court. It also tests whether internal “protect the office” instincts yield when prosecutors themselves flag a conflict and ask for an outside handoff to the state attorney general.
Diamond kept the broader office in the case after removing Krasner and Stiegler. That choice preserved continuity for the litigation while isolating the two officials he referred. The subsequent subpoenas move the dispute from judicial findings into DOJ process, still without charges.
Fox News carried the subpoena development as a follow-on to the referral coverage. The Justice Department’s no-comment posture and the DA office’s lack of an immediate response leave the public with the judge’s words, Krasner’s denial, and the sources’ description of why the grand jury papers went out.
For conservatives watching big-city prosecution and federal court integrity, the sequence is straightforward. A murder-case habeas fight. Conflict alarms. A refused handoff to the state AG. A federal judge’s referral citing possible false statements, perjury, obstruction, and conspiracy. Then DOJ grand jury subpoenas to the same office.
When a federal judge refers a district attorney for possible crimes and the Justice Department follows with grand jury subpoenas, the question is whether equal enforcement still reaches the people who run the local charging desk.
